Summary:

Connected tail lamps have emerged as one of the key features of modern automotive design. It aligns with current vehicle trends, giving a premium, hi-tech appearance and enhancing visibility for the drivers. (Original Equipment Manufacturers) OEM manufacturer utilizes connected tail lamps as a signature design element to establish and reinforce their brand identity. Assembly and integration of these components poses unique challenges due to Metal-to-plastic interfaces that generate audible noise such as squeak and rattle [1] and affect it affects the perceived quality of an occupant in electric vehicles (EVs). The misalignment of parts concerning geometric dimensioning and tolerancing (GD&T) specifications is addressed, as it contributes to increased micro-sliding between the interface and creates audible creaking sounds. This paper explores the influence of mounting fitment on noise generation and proposes a method to optimize the assembly process to reduce the stick-slip [2] interactions. Combining experimental testing with finite element analysis, the research focuses on identifying practical solutions by exploring mounting strategies with feasible assembly techniques [3] to prevent stick-slip interaction and improve overall perceived quality of the vehicle, for a comfortable driving experience
